Abstract:
Historically the sliding mode technique developed as a robust control
method characterised by a suite of feedback control laws and a decision
rule. The decision rule, termed the switching function, has as its
input some measure of the current system behaviour and produces as
an output the particular feedback controller which should be used
at that instant in time. The concept of sliding mode observers came
later. These observers have unique properties, in that the ability
to generate the so-called sliding motion on the error between the
measured plant output and the output of the observer ensures that
a sliding mode observer produces a set of state estimates that are
precisely commensurate with the actual output of the plant. It is
also the case that analysis of the average value of the applied observer
injection signal, the so-called equivalent injection signal, contains
useful information about the mismatch between the model used to define
the observer and the actual plant. These unique properties, coupled
with the fact that the discontinuous injection signals which were
perceived as problematic for many control applications have no disadvantages
for software-based observer frameworks, have generated a groundswell
of interest in sliding mode observer methods in recent years. This
lecture presents an overview of the sliding mode observer paradigm.

lecture:

Decentralised
sliding mode control for nonlinear interconnected systems with application
to a continuously stirred tank reactor

A
decentralised control strategy based on sliding mode techniques is
proposed for a class of nonlinear interconnected systems. Both matched
uncertainties in the isolated subsystems and mismatched uncertainties
associated with the interconnections are considered in the problem
formulation. Under mild conditions, sliding mode controllers for each
subsystem are designed in a decentralised manner by only employing
local information. Conditions are determined which enable information
on the interconnections to be employed within the decentralised controller
design process in order to reduce conservatism. The developed results
are applied to a continuously stirred-tank reactor (CSTR) system.
Simulation results are presented which demonstrate the effectiveness
of the approach.

About
the Speech:

A
Microgrid is an electrical distribution network consisted of distributed
generators, local loads, and energy storage systems that can operate
in grid-connected or islanded modes. Different technologies are combined
together, such us power converters, control, communications, optimization,
and so on. This way the energy can be generated and stored near to
the consumption points, improving the stability and reducing the losses
produced by the large power lines. The speech will cover not only
AC microgrids of conventional islanded systems to support AC loads
are demanded in several areas such as islands, rural and remote areas,
but also DC microgrids that may conform next low-voltage distribution
systems and microgrids will be based on DC, since many generators,
storages and loads operate in DC, such photovoltaics, batteries, supercapacitors,
LEDs, laptops, and electronic equipment. Important aspect on microgrid
research will be presented like modelling, control and operation,
energy storage, standard-based ICT and smart-metering, including wireless
communications, power line communications, bus signaling, and so on.
The application of smartmeters in microgrids will be highlighted.
Energy Management Systems and Optimization: Online and offline optimization
systems are required to enhance MicroGrid operation regarding energy
price, power losses, and economical aspects. Advanced technologies
like Multi-Agent Systems (MAS) will be presented as powerful tool
for distributed energy systems. Previous experiences in Danish electrical
system like the Cell Controller project used MAS technologies to balance
dispersed energy generation and consumption. Power quality aspects
will be introduced, such as voltage and current harmonics and unbalances
that have to be taken into account in a microgrid due to the existence
of nonlinear and/or single-phase loads. In such a case, the coordination
between power electronics converters is needed in order to enhance
system power quality in a cooperative way. Many examples of real microgrid
systems will be presented, such a demosite in Shanghai, China, a Smart
Home living lab in Denmark, and so on. Finally, one important application
in microgrids is maritime power systems, which include seaports, all
and hybrid electrical ships, ferries and vessels.

The
structure of the blood vessels in the retina is affected by diabetes,
hypertension, arteriosclerosis, retinopathy of prematurity (RoP),
and other conditions through modifications in shape, width, and tortuosity.
Quantitative analysis of the architecture of the vasculature of the
retina could assist in monitoring the evolution and stage of pathological
processes, their effects on the visual system, and the response to
treatment. Computer-aided detection, modeling, and quantitative analysis
of features related to the retinal vascular architecture could assist
in consistent, quantitative, and accurate assessment of pathological
processes by ophthalmologists. This seminar provides details on digital
image processing and pattern recognition techniques for the detection
and analysis of retinal blood vessels, detection of the optic nerve
head, modeling of shape for quantitative analysis of the temporal
arcades, measurement of the thickness of retinal vessels, and detection
of tortuous vessels. The techniques include methods for the detection
of curvilinear structures, the Hough transform, Gabor filters, phase
portraits, and specific algorithms for quantitative analysis of patterns
of diagnostic interest. Analysis of a dataset of retinal fundus images
of 19 premature infants with plus disease, a proliferative stage of
RoP, and 91 premature infants without plus disease resulted in an
area under the receiver operating characteristic curve of up to 0.98
using our parameter to quantify tortuosity. A graphical user interface
is being developed to facilitate clinical application of the methods.
The methods should assist in computer-aided diagnosis, follow up,
and clinical management of premature infants possibly affected by
RoP.

multilevel topologies have been reported for drive applications. But
still the most popular topology is the NPC three level, especially
for medium voltage drives applications. This shows that the industry
is still looking for some viable alternative to this, with reduced
power circuit complexity and with increased reliability for medium
voltage drives applications. The present lecture will focus on some

Wearable Physiological Monitoring System: Opportunities
and Challenges: Perspective of an Indian Context

ABSTRACT

Today’s healthcare technology has been revolutionized
by the development of wearable physiological monitoring systems, which
are being used for home healthcare delivery. The wearable system is
composed of specialized sensors, embedded into a wearable shirt for
data acquisition, along with a processing unit. The processed data
are sent to a monitoring station using wireless transmission. The
primary advantage of such system is the real-time continuous monitoring
of the signals by clinicians in the monitoring station, with the activation
of alarms during critical conditions. It is essential to monitor the
physiological signals continuously, so that immediate treatment can
be provided during emergency conditions. Health monitoring systems
become a hot topic and important research field today. Research on
health monitoring were developed for many applications such as military,
home care unit, hospital, sports training and emergency monitoring
system. This talk highlights a design of a rural centric based system
for the monitoring of physiological signals such as PPG,ECG using
a Cypress Programmable system on chip( PSoC ) processor/ NI Processor
. Home centric based system is the one that replaces the hospital
centric procedure for any consultation. The system comprises of a
wearable sensors with miniaturized chip programmed using PSoC Processor
and the chip performs the detection of the movement of the subject
using 2D Accelerometer, monitors the heart. The processed signals
are then sensed by a wireless communication module for transmitting
them to the nearby hospital. Three case studies are presented to showcase
the preliminary work carried out on the design and evaluation of the
physiological monitoring system

Estimation of Grid Harmonics in the Presence of Renewable Energy
Sources

Abstract:
Developments in the power electronics converter technology and control
methodologies have been accelerated many folds in recent years and
have made possible for the renewable energy sources (RESs) interconnection
to the utility grid. Penetration of RES into the electric power system
is growing rapidly across the globe owing to its environment friendly
and several other important characteristics. The use of power electronics
devices for interconnection of RES have resulted in severe harmonics
pollution. Harmonics, apart from creating problems of equipments overheating,
noise and communication interference at customer end, also increase
the reactive power requirement of converters, damage filter capacitances,
disturb controller functioning, increase losses in cables/transformers
/machines, etc., and introduce unwanted torque harmonics in the rotating
machines. The estimation of harmonics has become very important for
design, analysis, tariff, control and monitoring purposes. Fourier
transform based harmonics analyzer are available for the measurement
of harmonics spectrum, however, it suffers from many limitations.
As a result, intensive research has been focused on harmonics measurement
and estimation in the recent years. This presentation briefly covers
some of the important techniques of power system harmonics estimation
along with scope and future challenges.

Abstract: Displacement sensing and position sensing are necessary
for various applications such as assembly line testing, machine tool
usage, precise positioning for silicon wafer technology, applications
in automobiles and several others. A variety of sensors of different
types have been developed over the years to fulfill this requirement.
Displacement transducers based on (i) Hall effect sensor element,
(ii) inductive sensing element, and capacitive sensor element have
been developed. In addition to all the above sensors, resistive potentiometric
type displacement transducers are in vogue for a variety of applications
where linear or angular position sensing. Many of these sensors are
of contact type. Contact type displacement sensors suffer from wear
and tear and hence have limited operation life. Recent trend is to
develop non contact linear and angular displacement sensors. The talk
will highlight the research done and research being carried out at
present at IIT Madras in developing non contact displacement sensors.
